When you use --gui=qt or --matplotlib=qt, IPython can work with either PyQt4 or PySide. There are three options for configuration here, because PyQt4 has two APIs for QString and QVariant: v1, which is the default on Python 2, and the more natural v2, which is the only API supported by PySide. v2 is also the default for PyQt4 on Python 3. IPython’s code for the QtConsole uses v2, but you can still use any interface in your code, since the Qt frontend is in a different process. IPython and the associated Jupyter Notebook offer efficient interfaces to Python for data analysis and interactive Table of contents. 1 A Tour of Interactive Computing with Jupyter and IPython When running inside IPython with an integrated event loop, a GUI application should not start its own event loop. This means that applications that are meant to be used both in IPython and as standalone apps need to have special code to detects how the application is being run. We highly recommend using IPython’s support for this. Since the details vary slightly between toolkits, we point you to the various examples in our source directory examples/IPython Kernel/gui/ that demonstrate these capabilities.

IPython extends the debugger with a few useful additions, like coloring of tracebacks. The debugger will adopt the color scheme selected for IPython. I'm using ipython3, installed on Ubuntu with apt-get. I can't use the paste magic function, it complains about missing Tkinter. But I do have Tkinter and the same thing works fine on ipython (2). What gives %pdef <object>: Print the call signature for any callable object. If the object is a class, print the constructor information.

The where command has also been extended to take as argument the number of context line to show. This allows to a many line of context on shallow stack trace: learnpython.org is a free interactive Python tutorial for people who want to learn Python, fast

$ ipython --TerminalIPythonApp.matplotlib='qt' Note that in the second form, you must use the equal sign, as the expression is evaluated as an actual Python assignment. While in the above example the short form is more convenient, only the most common options have a short form, while any configurable variable in IPython can be set at the command-line by using the long form. This long form is the same syntax used in the configuration files, if you want to set these options permanently.Download the file for your platform. If you're not sure which to choose, learn more about installing packages.For output that is returned from actions, a system similar to the input cache exists but using _ instead of _i. Only actions that produce a result (NOT assignments, for example) are cached. If you are familiar with Mathematica, IPython’s _ variables behave exactly like Mathematica’s % variables.IPython will treat any line whose first character is a % as a special call to a ‘magic’ function. These allow you to control the behavior of IPython itself, plus a lot of system-type features. They are all prefixed with a % character, but parameters are given without parentheses or quotes.This allows you to easily cut and paste multi line interactive prompts by printing them out: they print like a clean string, without prompt characters. You can also manipulate them like regular variables (they are strings), modify or exec them.

IPython is an advanced interactive Python shell. When you invoke it, you will get a Python interactive interpreter (like running Python), but with some features that make it much easier and more pleasant..

  3. IPython allows non-blocking interaction with Tkinter, PyGTK, PyQt/PySide and wxPython (the standard Python shell only allows interaction with Tkinter). IPython can interactively manage parallel computing clusters using asynchronous status callbacks and/or MPI. IPython can also be used as a system shell replacement.[7] Its default behavior is largely similar to Unix shells, but it allows customization and the flexibility of executing code in a live Python environment. Using IPython as a shell replacement is less common and it is now recommended to use Xonsh which provide most of the IPython feature with better shell integrations.
